Add a note about not touching errno and warn about previous drafts
of the standard which changed the level of indirection to the thread
argument. POSIX had a bit of trouble deciding what to do. So anyone
coding to both draft 4 and draft 10 (the final draft) will get burnt
by this function. I did. Grrr.
_KPOSIX_PRIORITY_SCHEDULING options to work. Changes:
Change all "posix4" to "p1003_1b". Misnamed files are left
as "posix4" until I'm told if I can simply delete them and add
new ones;
Add _POSIX_PRIORITY_SCHEDULING system calls for FreeBSD and Linux;
Add man pages for _POSIX_PRIORITY_SCHEDULING system calls;
Add options to LINT;
Minor fixes to P1003_1B code during testing.
ESCAPE and `~ are swapped
CTRL and CAPS LOCK are swapped
BACKSPACE and DELETE are swapped
Suitable for keymap=us.unix in your rc.conf file or for setting on the
fly with kbdcontrol -l us.unix. This is the keyboard layout of many of
the more traditional unix workstations and terminals that have been around
for a very long time. Older Sun keyboards and VT100's had a layout
very similar to the PC, with the above exceptions.

`BINFORMAT=foo make checkdpadd' in /usr/src now reports only 2 false
negatives (in libss and init). (BINFORMAT=foo is to turn off better
handling of the a.out case.)
Changes to support building with _POSIX_SOURCE set to 199309L:
1. Add sys/_posix.h to handle those preprocessor defs that POSIX
says have effects when defined before including any header files;
2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE
3. Add _POSIX4_VISIBLE_HISTORICALLY for pre-existing BSD features now
defined in POSIX. These show up when:
_POSIX_SOURCE and _POSIX_C_SOURCE are not set or
_POSIX_C_SOURCE is set >= 199309L
and vanish when:
_POSIX_SOURCE is set or _POSIX_C_SOURCE is < 199309L.
4. Explain these in man 9 posix4;
5. Include _posix.h and conditionalize on new feature test.
- the two `_EXTRADEPEND::' targets potentially clobbered each other for
`make -jN'. In practice, the output for the second target sometimes
disappeared.
- bogus dependencies were generated for static libraries.
headers in ${SRCS}, as in bsd.lmod.mk and bsd.prog.mk. This helps
`make [-j]' work when .depend doesn't exist. Even plain `make'
sometimes only worked because of magic ordering in ${SRCS}.
use the default without losing any (currently unused) features.
(CLEANDIRS is only used by for libgmp and libmp via bsd.lib.mk, and
only documented everywhere it is supported except of course where it
is actually used.)
